FIELD OF THE INVENTION

The present invention generally relates to the field of insect inhibitory proteins. In particular, the present invention relates to proteins exhibiting insect inhibitory activity against agriculturally relevant pests of crop plants and seeds, particularly Lepidopteran and/or Hemipteran species of insect pests.

BACKGROUND OF THE INVENTION

Insect inhibitory proteins derived from Bacillus thuringiensis (Bt) are known in the art. These proteins are used to control agriculturally relevant pests of crop plants by spraying formulations containing these proteins onto plants/seeds or by expressing these proteins in plants and in seeds.

Only a few Bt proteins have been developed for use in formulations or as transgenic traits for commercial use by farmers to control Coleopteran and Lepidopteran pest species, and no Bt proteins have been used for commercial control of Hemipteran pest species. Certain Hemipteran species, particularly Lygus bugs, are pests of cotton and alfalfa, and typically are only controlled using broad spectrum chemistries, e.g., endosulfan, acephate, and oxamyl, which can persist and harm the environment. However, dependence on a limited number of these Bt proteins can result in occurrence of new pests resistant to these proteins, and reliance on broad-spectrum chemistries can harm the environment.

Hence, there is a continuous need for the discovery and commercial development of new proteins active against pests of crop plants.

SUMMARY OF THE INVENTION

The present invention provides a novel group, i.e. a new genus, of insect inhibitory polypeptides (toxin proteins) which are shown to exhibit inhibitory activity against one or more pests of crop plants. Each of the proteins can be used alone or in combination with each other and with other Bt proteins and toxic agents in formulations and in planta, thus providing alternatives to Bt proteins and insecticide chemistries currently in use in agricultural systems.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates the primary structure of proteins exemplified in this application, showing the features and motifs characteristic for each of the proteins in this genus. Each protein is depicted by name, SEQ ID NO, structural schematic, and amino acid length (i.e., number of amino acids), and organized into groups or clusters based on amino acid identity between the various proteins. The proteins within a group generally exhibit at least about 90% amino acid identity. Generally, most proteins in the genus of novel proteins disclosed herein contain, in operable linkage within the polypeptide, at least one of each of six different signature motifs (M) or motif peptide segments, each motif being unique to this genus of proteins. The motifs are referenced herein and consecutively numbered as M0, M1, M2, M3, M4 and M5. The M0 motif is proximal to the amino terminus of each protein toxin, and the M5 motif is positioned most proximal to the carboxy terminus of each protein toxin. The M5 motif can also be present in more than one copy in each protein. Each motif contains a core amino acid segment unique to that particular motif. The presence of any of the referenced motif peptide segments in a protein derived from Bacillus thuringiensis or related species of bacilli, and the observation for such protein of toxic activity directed to one or more species of Hemiptera and/or Lepidoptera, is sufficient to provide for classification of such protein as being within the scope of the present invention, particularly if the full length of the protein amino acid sequence exhibits at least about 47% or greater identity to any of the proteins embodied herein including proteins as set forth in SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, SEQ ID NO:10, SEQ ID NO:12, SEQ ID NO:14, SEQ ID NO:16, SEQ ID NO:18, SEQ ID NO:20, SEQ ID NO:22, or SEQ ID NO:24. Secondary motifs observed within each of the major motifs M0-M5 in certain of the proteins of the present invention are referenced herein as M1t, M2t, and M4t. Certain of the proteins also contain proteolytic cleavage sites KK, EH, TF, and FG, the relative positions of each being marked in applicable proteins represented in FIG. 1 as [1], [2], [3], and [4], respectively (the two letters represent the two amino acid residues bracketing the cleavage site), are features of proteins within the scope of this invention.

FIG. 2 is a Venn diagram depicting the activity profile of the proteins of the present invention. Circle [A] represents Lepidopteran-active proteins, while Circle [B] represents Hemipteran-active proteins. Area [‘c’] is an intersection of Circles [A] and [B], which represents proteins that tested positive for activity against both Lepidopteran and Hemipteran insects. Area [‘a’] is [A] minus [‘c’], which represents proteins that tested positive for activity against Lepidopteran insects but not positive for any activity against Hemipteran species indicated at the dose at which Lepidopteran activity was observed. Area [‘b’] is [B] minus [‘c’], which represents proteins that tested positive for activity against Hemipteran insects but not positive for activity against the Lepidopteran species indicated at the dose at which Hemipteran species activity was observed.

DETAILED DESCRIPTION OF THE INVENTION

Bacillus thuringiensis (Bt) proteins are a rich source of diverse toxin proteins; however, many problems exist in the process of identifying new Bt toxins. Screening methods that involve morphological typing of Bt strains, (e.g. structural analysis of parasporal inclusion bodies, cell coat morphology, visible color, and morphology under different growing conditions), do not provide a good correlation with the presence of novel toxic proteins. Additionally, screening methods that involve highly matrixed bioassay processes for identifying proteins with toxic properties yield inconsistent results. Such processes include but may not be limited to testing proteins expressed at various stages of Bt growth and development, testing different Bt protein preparations, testing Bt proteins activated by various proteolytic treatments, testing Bt proteins with other ancillary proteins, and testing Bt proteins under various induction conditions. Some screening methods rely on structural and functional design, which require very labor and skill intensive procedures to elucidate structure/function relationships, and often these protocols can only be effective when carried out on fully elucidated toxins. In view of the inherent problems in finding new Bt toxin proteins, screening for genes encoding Bt toxin proteins has changed due to recent improvements in bioinformatics and genome sequence capabilities.

The inventors herein have taken advantage of high throughput sequencing and improvements in bioinformatics capabilities to screen Bt genomes for novel protein-encoding Bt toxin genes, which are then cloned and expressed in acrystalliferous Bt strains to produce protein samples for insect inhibitory activity screening. As described herein and using this method, a novel protein genus has been discovered and exemplary proteins exhibiting insecticidal activity against Hemipteran and/or Lepidopteran species. Those skilled in the art will appreciate that the teaching of the present invention enables related gene/protein members to be identified or engineered that exhibit the properties and features of the proteins of the present invention.

The polypeptides/proteins of the present invention are related by source or origin (from B.t. strains of bacteria), by biological toxin activity against insect pests within the orders Hemiptera and/or Lepidoptera, by primary structure (conserved amino acid sequences), and by length (from about 300 to about 400 amino acids).

Proteins of the present invention, and proteins that resemble the proteins of the present invention, can be identified by comparison to each other using various computer based algorithms known in the art. Amino acid identities reported herein are a result of a Clustal W alignment using these default parameters: Weight matrix: blosum, Gap opening penalty: 10.0, Gap extension penalty: 0.05, Hydrophilic gaps: On, Hydrophilic residues: GPSNDQERK, Residue-specific gap penalties: On (Thompson et al (1994) Nucleic Acids Research, 22:4673-4680).

It is intended that a recombinant polypeptide exhibiting insect inhibitory activity against a Lepidopteran and/or Hemipteran insect species is within the scope of the present invention if an alignment of the polypeptide with any of SEQ ID NO:2 (TIC1498), SEQ ID NO:4 (TIC1415), SEQ ID NO:6 (TIC1497), SEQ ID NO:8 (TIC1886), SEQ ID NO:10 (TIC1925), SEQ ID NO:12 (TIC1414), SEQ ID NO:14 (TIC1885), SEQ ID NO:16 (TIC1922), SEQ ID NO:18 (TIC1422), SEQ ID NO:20 (TIC1974), SEQ ID NO:22 (TIC2032), SEQ ID NO:24 (TIC2120), SEQ ID NO:26 (TIC1362), SEQ ID NO:136 (TIC2335), and SEQ ID NO:138 (TIC2334) results in at least 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223, 224, 225, 226, 227, 228, 229, 230, 231, 232, 233, 234, 235, 236, 237, 238, 239, 240, 241, 242, 243, 244, 245, 246, 247, 248, 249, 250, 251, 252, 253, 254, 255, 256, 257, 258, 259, 260, 261, 262, 263, 264, 265, 266, 267, 268, 269, 270, 271, 272, 273, 274, 275, 276, 277, 278, 279, 280, 281, 282, 283, 284, 285, 286, 287, 288, 289, 290, 291, 292, 293, 294, 295, 296, 297, 298, 299, 300, 301, 302, 303, 304, 305, 306, 307, 308, 309, 310, 311, 312, 313, 314, 315, 316, 317, 318, 319, 320, 321, 322, 323, 324, 325, 326, 327, 328, 329, 330, 331, 332, 333, 334, 335, 336, 337, 338, 339, 340, 341, 342, 343, 344, 345, 346, 347, 348, 349, 350, 351, 352, 353, 354, 355, 356, 357, 358, 359, 360, 361, 362, 363, 364, 365, 366, 367, 368, 369, 370, 371, 372, 373, 374, 375, 376, 377, 378, 379, 380, 381, 382, 383, 384, 385, or 386 amino acid identities.

The presence of this M5 motif or its core, or of a peptide segment exhibiting at least 80% amino acid sequence identity to this M5 motif, alone or in combination with other motifs described herein, in a particular protein derived from Bt is determinative that the protein is a member of the genus of proteins described herein, particularly when the protein is also shown to exhibit insect inhibitory properties. The polypeptides/proteins of the present invention are related by this M5 motif which can occur once as exemplified by SEQ ID NOs: 8, 12, 18, and 20; as a double repeat as exemplified by SEQ ID NOs: 2, 14, and 24; and as a triple repeat as exemplified by SEQ ID NOs: 4, 6, 10, 12, 16, and 22. Interestingly, TIC1414 and TIC1922 can be aligned with 100% identity with reference to TIC1414 (Table 1), which is possible because the difference between TIC1414 and TIC1922 are two repeats of the M5 motif (gaps allowed in the pair-wise alignment).

The present invention provides a recombinant polypeptide comprising a peptide segment exhibiting at least 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, or 100% amino acid sequence identity to an amino acid sequence selected from the group consisting of SEQ ID NO:31 (motif M0), SEQ ID NO:48 (motif M1), SEQ ID NO:53 (motif M2), SEQ ID NO:62 (motif M3), SEQ ID NO:65 (motif M4), SEQ ID NO:141 (motif M5), SEQ ID NO:70 (motif M10, SEQ ID NO:87 (motif M2t), SEQ ID NO:120 (motif M40, and any combination thereof. Such polypeptide exhibits insect inhibitory activity against Lepidopteran and/or Hemipteran species. As used herein, the term “insect inhibitory activity” refers to activity of a protein, or a fragment thereof, effective in inhibiting a pest, preferably a pest of one or more crop plants, when provided in the diet of the pest and ingested by the target (intended) pest. Pests of crop plants include nematodes and arthropods, including insects. Proteins of the present invention are effective in inhibiting the growth, development, viability or fecundity of a particular target pest, particularly an insect pest, including but not limited to insects of the orders Lepidoptera and Hemiptera.

In certain embodiments, the insect inhibitory polypeptides/proteins contain amino acid segments exhibiting at least 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, or 100% identity to any one or more of the signature motifs (SEQ ID NOs:31-122, 142 and 143) of the proteins of the present invention.

In certain embodiments, the recombinant polypeptide comprises the amino acid sequence as set forth in SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, SEQ ID NO:10, SEQ ID NO:12, SEQ ID NO:14, SEQ ID NO:16, SEQ ID NO:18, SEQ ID NO:20, SEQ ID NO:22, SEQ ID NO:24, SEQ ID NO:26, SEQ ID NO:136, or SEQ ID NO:138, or an insect inhibitory fragment thereof. Exemplary insect inhibitory fragments include, but not limited to, those comprising the amino acid sequence as set forth in SEQ ID NO:123, SEQ ID NO:124, SEQ ID NO:125, and SEQ ID NO:126.

Additional signature motifs include proteolytic cleavage sites “KK”, “EH”, “TF”, and “FG”, the relative positions of each shown as [1], [2], [3], and [4], respectively in FIG. 1.

An additional signature motif includes an N-terminal consensus sequence as set forth in SEQ ID NO:142, where X₁ is A or E, X₂ is N or D, X₃ is Q or E, and X₄ is S or L, shared by proteins that are members of the genus of proteins exemplified herein, with the exception of the protein having the amino acid sequence as set forth in SEQ ID NO:26. Forward oligonucleotide primers, e. g., SEQ ID NO:127, SEQ ID NO:129, SEQ ID NO:131, and SEQ ID NO:133 can be designed to hybridize to the plus strand of the DNA sequence encoding for the N-terminal consensus sequence of proteins of the present invention. The C-terminal consensus sequence as set forth in SEQ ID NO:143, where X₁ is H or E, and X₂ is N or Y, is a signature motif shared by proteins of the present invention. Reverse oligonucleotide primers, e. g., SEQ ID NO:128, SEQ ID NO:130, SEQ ID NO:132, and SEQ ID NO:134, can be designed to hybridize to the minus strand of the DNA sequence encoding for the C-terminus consensus sequence of proteins of the present invention. Oligonucleotide primers can be designed to hybridize to plus or minus strands of any one or more of the signature motifs (SEQ ID NOs:31-122, 140 and 141) of the proteins of the present invention.

When combined, forward and reserve primers can be used to amplify nucleotide sequences encoding proteins (or fragments thereof) of the present invention.

The proteins of the present invention can be used to produce antibodies that bind specifically to this genus of proteins and can be used to screen for and to find other members of the genus.

Nucleotide sequences encoding these proteins can be used as probes and primers for screening to identify other members of the genus using thermal or isothermal amplification and/or hybridization methods, e. g., oligonucleotides as set forth in SEQ ID NOs:127-134, and oligonucleotides hybridizing to sequence encoding the signature motifs of the present invention. Nucleotide sequence homologs, i.e., insecticidal proteins encoded by nucleotide sequences that hybridize to each or any of the sequences disclosed herein under stringent hybridization conditions, are specifically intended to be included within the scope of the present invention. The present invention also provides a method for detecting a first nucleotide sequence that hybridizes to a second nucleotide sequence, wherein the first nucleotide sequence encodes an insecticidal protein or insecticidal fragment thereof and hybridizes under stringent hybridization conditions to the second nucleotide sequence. In such case the second nucleotide sequence can be any of the sequences disclosed herein under stringent hybridization conditions. Nucleotide coding sequences hybridize to one another under appropriate hybridization conditions and the proteins encoded by these nucleotide sequences cross react with antiserum raised against any one of the other proteins. Stringent hybridization conditions, as defined herein, comprise at least hybridization at 42° C. followed by two washes for five minutes each at room temperature with 2×SSC, 0.1% SDS, followed by two washes for thirty minutes each at 65° C. in 0.5×SSC, 0.1% SDS. Of course, one skilled in the art will recognize that, due to the redundancy of the genetic code, many other sequences are capable of encoding such related proteins, and those sequences, to the extent that they function to express insecticidal proteins either in Bacillus strains or in plant cells, are intended to be encompassed by the present invention, recognizing of course that many such redundant coding sequences will not hybridize under these conditions to the native Bt sequences encoding TIC1498, TIC1415, TIC1497, TIC1886, TIC1925, TIC1414, TIC1885, TIC1922, TIC1422, TIC1974, TIC2032, TIC2120, TIC1362, TIC2335, and TIC2334.

In certain embodiments, a recombinant polypeptide exhibiting insect inhibitory activity against a Lepidopteran and/or Hemipteran insect species is within the scope of the present invention, which polypeptide is encoded by a polynucleotide segment that hybridizes under stringent hybridization conditions to one or more of the nucleotide sequences set forth in any of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:135, or SEQ ID NO:137, or the complement thereof.

An aspect of this invention provides methods for discovering related proteins, and such methods include the sequencing of Bt genomes, assembly of sequence data, the identification and cloning of Bt genes encoding such insect inhibitory proteins, and the expression and testing of new Bt proteins to assay for insect inhibitory activity. Another aspect of this invention employs molecular methods to engineer and clone commercially useful proteins comprising chimeras of proteins and improved variants from the genus of insect inhibitory proteins, e. g., the chimeras can be assembled from segments in each of the various proteins that are within the spaces between the signature motifs to derive improved embodiments. The proteins of the present invention can be subjected to alignment to each other and to other Bt insect inhibitory proteins, and segments of each such protein can be identified that may be useful for substitution between the aligned proteins, resulting in the construction of chimeric proteins. Such chimeric proteins can be subjected to pest bioassay analysis and characterized for the presence of increased bioactivity or expanded target pest spectrum compared to the parent proteins from which each such segment in the chimera was derived. The insect inhibitory activity of the polypeptides can be further engineered for improved activity to a particular pest or to a broader spectrum of pests by swapping domains or segments with other proteins.

One skilled artisan understands the concept of amino acid substitution, and recognizes that this requires experimentation that is not routine, as there are amino acid positions that can accept substitution without apparent affect to the structure or function of the protein; however, in surprising circumstances, even a conservative substitution may be determined to significantly alter the structure or function of the protein, and it is often unknown with precision the positions in the amino acid segments that would accept such changes. Accordingly, amino acid substitutions at positions along the length of the protein sequence that affect function can be identified by alanine scanning mutagenesis, and such positions can often be useful for points of amino acid insertions and/or deletions, or N- or C-terminal deletions. Accordingly, the proteins of the present invention include functionally equivalent fragments (N- or C-terminal deletions) of the proteins represented by the amino acid sequences of the present invention. N-terminal protein fragments (SEQ ID NOs:123-126, 16) of TIC1497 and TIC1922 have demonstrated insect inhibitory activity (Table 2 and Examples 6, 10, and 11, respectively). Corresponding N-terminal protein fragments for any member of the genus is contemplated.

Proteins functionally equivalent (having substantially equivalent insect inhibitory activity) to the proteins of the present invention include proteins with conservative amino acid substitutions in the protein sequences of the present invention. In such amino acid sequences, one or more amino acids in the starting sequence is (are) substituted with another amino acid(s), the charge and polarity of which is similar to that of the native amino acid, i. e., as exemplified herein a conservative amino acid substitution, resulting in a conservative change from the perspective of charge and polarity, but which may result in a change in the bioactivity of the protein, preferably increasing the activity of the protein compared to the starting protein with the original amino acid at such positions, or resulting in a change in the variant protein with reference to the spectrum of biological activity and without any loss of insect inhibitory activity. An example of proteins that can entertain substituted amino acids or terminal deletions to obtain biological equivalents include, but are not limited to, the protein sequence as set forth in any of SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, SEQ ID NO:10, SEQ ID NO:12, SEQ ID NO:14, SEQ ID NO:16, SEQ ID NO:18, SEQ ID NO:20, SEQ ID NO:22, SEQ ID NO:24, SEQ ID NO:26, and SEQ ID NOs:123-126.

Enrichment of the proteins of the present invention either in plants or by a process that includes culturing recombinant Bt cells under conditions to express/produce recombinant polypeptide/proteins of the present invention is contemplated. Such a process can include preparation by desiccation, lyophilization, homogenization, extraction, filtration, centrifugation, sedimentation, or concentration of a culture of recombinant Bacillus thuringiensis cells expressing/producing said recombinant polypeptide. Such a process can result in a Bt cell extract, cell suspension, cell homogenate, cell lysate, cell supernatant, cell filtrate, or cell pellet. By obtaining the recombinant polypeptides/proteins so produced, a composition that includes the recombinant polypeptides/proteins can include bacterial cells, bacterial spores, and parasporal inclusion bodies and can be formulated for various uses, including agricultural insect inhibitory spray products or as insect inhibitory formulations in diet bioassays.

It is intended that an insect inhibitory composition/formulation comprising the aforementioned recombinant polypeptide/protein is within the scope of the present invention. In certain embodiments, such composition may further comprise at least one pesticidal agent that exhibits insect inhibitory activity against the same Lepidopteran and/or Hemipteran insect species but is different from the recombinant polypeptide. Such agent is selected from the group consisting of an insect inhibitory protein, an insect inhibitory dsRNA molecule, and an ancillary protein. Examples of such agents include, but are not limited to, a TIC807 protein, a TIC853 protein, a AXMI-171 protein, and a Cry51Aa1 protein. Other compositions are contemplated for combining with the proteins of the present invention, and with the combinations of proteins provided above. For example, topically applied pesticidal chemistries that are designed for controlling pests that are also controlled by the proteins of the present invention can be used with the proteins of the present invention in seed treatments, spray on/drip on/or wipe on formulations that can be applied directly to the soil (a soil drench), applied to growing plants expressing the proteins of the present invention, or formulated to be applied to seed containing one or more transgenes encoding one or more of the proteins of the present invention. Such formulations for use in seed treatments can be applied with various stickers and tackifiers known in the art. Such formulations may contain pesticides that are synergistic in mode of action with the proteins of the present invention, meaning that the formulation pesticides act through a different mode of action to control the same or similar pests that are controlled by the proteins of the present invention, or that such pesticides act to control pests within a broader host range, such as lepidopteran or Hemipteran species or other plant pest species such as coleopteran species that are not effectively controlled by the proteins of the present invention.

The aforementioned composition/formulation can further comprise an agriculturally-acceptable carrier, such as a bait, a powder, dust, pellet, granule, spray, emulsion, a colloidal suspension, an aqueous solution, a Bacillus spore/crystal preparation, a seed treatment, a recombinant plant cell/plant tissue/seed/plant transformed to express one or more of the proteins, or bacterium transformed to express one or more of the proteins. Depending on the level of insect inhibitory or insecticidal inhibition inherent in the recombinant polypeptide and the level of formulation to be applied to a plant or diet assay, the composition/formulation can include various by weight amounts of the recombinant polypeptide, e.g. from 0.0001% to 0.001% to 0.01% to 1% to 99% by weight of the recombinant polypeptide.

The proteins of the invention can be combined in formulations for topical application to plant surfaces, to the soil, in formulations for seed treatments, in formulations with other agents toxic to the target pests of Hemipteran and Lepidopteran species. Such agents include but are not limited to, a TIC807 protein, a TIC853 protein, a AXMI-171 protein, and a Cry51Aa1 protein which each are effective in controlling the same Hemipteran pests that are controlled by the insect inhibitory proteins of the present invention.

It is also intended that a method of controlling a Lepidopteran and/or Hemipteran species pest is within the scope of the present invention. Such method comprises the steps of contacting the pest with an insect inhibitory amount of the recombinant polypeptide/protein. In certain embodiments, Lepidopteran and Hemipteran species pest is in a crop field.

An embodiment of the invention includes recombinant polynucleotides that encode the insect inhibitory protein members of the genus. With reference to a “recombinant” polynucleotide, it is intended that a polynucleotide molecule is made by human means or intervention through molecular biology engineering techniques, which can include the amplification or replication of such molecules upon introduction into a host cell, and the subsequent extraction and/or purification of the polynucleotide from the representative host cell. Polynucleotide embodiments of the present invention include ribonucleic acids (RNA) and deoxyribonucleic acids (DNA). Proteins of the present invention can be expressed from DNA constructs in which the open reading frame encoding the protein is operably linked to elements such as a promoter and any other regulatory elements functional for expression in that particular system for which the construct is intended. For example, plant-expressible promoters can be operably linked to protein encoding sequences for expression of the protein in plants, and Bt-expressible promoters can be operably linked to the protein encoding sequences for expression of the protein in Bt. Other useful elements that can be operably linked to the protein encoding sequences include, but are not limited to, enhancers, introns, protein immobilization tags (HIS-tag), target sites for post-translational modifying enzymes, dsRNA coding segments, siRNAs, miRNAs, ribosomal binding sites, leader elements, and miRNA target sites.

Exemplary recombinant polynucleotide molecules provided herewith include, but are not limited to, SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:13, SEQ ID NO:15, SEQ ID NO:17, SEQ ID NO:19, SEQ ID NO:21, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:27, SEQ ID NO:28, SEQ ID NO:29, SEQ ID NO:30, and SEQ ID NO:135.

An aspect of the invention provides a recombinant DNA construct that includes one or more aforementioned polynucleotides, which can additionally be engineered with transcribable or non-transcribable regions or both. Such regions are operably assembled to promote expression of DNA to RNA through either in vivo or in vitro systems, thereby producing the novel RNA transcript embodiments of the present invention. The present invention features RNA transcripts that include, but are not limited to, the protein-encoding RNA and additional RNA regions that are translatable, non-translatable, or both. Such additional RNA regions include translatable regions engineered to translate to terminal or intra-peptide regions, and non-translatable regions engineered to either promote transcription, translation, or both.

In certain embodiments, the aforementioned recombinant DNA construct is in an expression cassette for use in an E. coli or Bt expression system. Expression cassettes are typically designed with a promoter at the 5′ end of the cassette, upstream of a desired polynucleotide segment encoding a protein of the present invention. A promoter can consist of multiple different promoter elements operably linked to provide for the initiation of transcription of the sequences encoding a protein of the invention. The DNA sequence consisting of the promoter-protein-encoding DNA can be operably linked at its 3′ end to a transcriptional termination signal sequence functional in an E. coli and/or Bt cell to produce the recombinant DNA construct.

In certain embodiments, the aforementioned recombinant DNA construct is in an expression cassette for expression in plants. Expression cassettes are designed with a promoter at the 5′ end of the cassette, upstream of a desired polynucleotide segment encoding a protein of the present invention. 5′ untranscribed DNA can comprise a promoter which can consist of multiple different promoter and enhancer elements operably linked to provide for the initiation of transcription of downstream sequences including sequences encoding the polypeptides of the invention. One or more transcribed but non-translated DNA sequence(s) can be operably linked 3′ to the promoter in the expression cassette, including leader and/or intron sequence(s). An intron sequence is optionally provided 3′ to the leader sequence or in some cases within the open reading frame encoding the desired protein. A polynucleotide segment encoding an optional translocation polypeptide (a signal peptide or a chloroplast transit peptide, for example) may be inserted 5′ to the coding sequence of the protein of the present invention for localizing the protein of the invention to a particular subcellular position. The nucleotide sequence encoding the protein of the present invention is optionally operably positioned within the aforementioned expression cassette, along with any requisite operably linked polyadenylation (polyA) and/or transcriptional termination sequence functional in plant cells. The aforementioned elements are arranged contiguously and can be used in various combinations depending on the desired expression outcome.

The present invention features promoters functional in plants including, but not limited to, constitutive, non-constitutive, spatially-specific, temporally-specific, tissue-specific, developmentally-specific, inducible, and viral promoters. Examples of promoters functional in plants include corn sucrose synthetase 1, corn alcohol dehydrogenase 1, corn light harvesting complex, corn heat shock protein, pea small subunit RuBP carboxylase, Ti plasmid mannopine synthase, Ti plasmid nopaline synthase, petunia chalcone isomerase, bean glycine rich protein 1, Potato patatin, lectin, CaMV 35S, the S E9 small subunit RuBP carboxylase, carnation etched ring virus, and dahlia mosaic virus promoter.

A recombinant DNA construct comprising the protein encoding sequences can also further comprise a region of DNA that encodes for one or more insect inhibitory agents which can be configured to concomitantly express or co-express with DNA sequence encoding the protein of the present invention, a protein different from the aforementioned protein, an insect inhibitory dsRNA molecule, or an ancillary protein. Ancillary proteins include co-factors, enzymes, binding-partners, or other insect inhibitory agents that function synergistically to aid in the effectiveness of an insect inhibitory agent, for example, by aiding its expression, influencing its stability in plants, optimizing free energy for oligomerization, augmenting its toxicity, and increasing its spectrum of activity.

A recombinant polynucleotide or recombinant DNA construct comprising the protein-coding sequence can be delivered to host cells by vectors. Methods for transferring recombinant DNA constructs to and from host cells, including E. coli, B. thuringiensis, and Agrobacterium species, are known in the art. Such vectors are designed to promote the uptake of vector DNA and to further provide expression of DNA to RNA to protein in in vitro or in vivo systems, either transiently or stably. Examples of the vectors include, but are not limited to, a plasmid, baculovirus, artificial chromosome, virion, cosmid, phagemid, phage, or viral vector. Such vectors can be used to achieve stable or transient expression of the protein encoding sequence in a host cell; and, if the case may be, subsequent expression to polypeptide. An exogenous recombinant polynucleotide or recombinant DNA construct that comprises the protein encoding sequence and that is introduced into a host cell is also referred to herein as a “transgene”.

Plasmids can be designed to replicate in E. coli or B. thuringiensis, or both. Such plasmids contain genetic elements that allow for the replication and maintenance of such plasmids and for the expression of transgenes, e.g. aforementioned recombinant DNA constructs, in either species.

Plant transformation vectors can be designed to allow for the Agrobacterium-mediated transfer of a T-DNA, i.e. transferred DNA comprising aforementioned recombinant DNA constructs. Such plant transformation vectors contain genetic elements that allow for the replication and maintenance of such plasmid vectors in E. coli and/or Agrobacterium and are essential for transfer of the T-DNA into a plant genome.

Transgenic host cells comprising recombinant DNA constructs encoding toxin proteins of the present invention are also contemplated. A transgenic host cell can be further defined as a prokaryotic host cell, i.e. a bacterial cell, e. g., Bacillus thuringiensis, Bacillus subtilis, Bacillus megaterium, Bacillus cereus, Bacillus laterosperous, Escherichia, Salmonella, Agrobacterium, Pseudomonas, or Rhizobium cell, or a eukaryotic host cell, e. g., a plant cell, and each of these types of cells is also referred to herein as a microbial cell, a microbe, or a microorganism.

As used herein a “host cell” means a cell that is transformed or transfected with exogenous recombinant DNA, e.g. by electroporation or by Agrobacterium-mediated transformation or by bombardment using microparticles coated with recombinant DNA, or by transduction or by plasmid transfer or by other means. A host cell of this invention can be a transformed bacterium, e.g. E. coli host cell or Bt host cell or Agrobacterium host cell, or a plant host cell.

Accordingly, a host cell of can be an originally-transformed plant cell that exists as a microorganism or as a progeny plant cell that is regenerated into differentiated tissue, e. g., into a transgenic plant with stably-integrated, non-natural recombinant DNA, or seed or pollen derived from a progeny transgenic plant. As used herein a “transgenic plant” includes a plant, plant part, plant cells or seed whose genome has been altered by the stable integration of recombinant DNA. A transgenic plant includes a plant regenerated from an originally-transformed plant cell and progeny transgenic plants from later generations or crosses of a transformed plant. Accordingly, examples of plant parts are leaf, a branch, a bark, a blade, a pollen grain, a stalk, a cell, a stem, a flower, a sepal, a fruit, a root, or a seed.

Transgenic plants expressing the protein(s) of the invention exhibit pest tolerance. Such plants and its cells include alfalfa, banana, barley, bean, berry, brassica, broccoli, cabbage, cactus, carrot, cassava, castor, cauliflower, celery, chickpea, Chinese cabbage, citrus, clover, coconut, coffee, corn, cotton, cucumber, cucurbit, Douglas fir, eggplant, eucalyptus, flax, fruit, garlic, grape, hops, kapok, leek, legume, lettuce, Loblolly pine, melons, millets, nut, oat, olive, onion, ornamental, palm, pasture grass, pea, peanut, pepper, pigeonpea, pine, poplar, potato, pumpkin, Radiata pine, radish, rapeseed, rice, rootstocks, rye, safflower, shrub, sorghum, Southern pine, soybean, spinach, squash, strawberry, succulent, sugar beet, sugarcane, sunflower, sweet corn, sweet gum, sweet potato, switchgrass, tea, tobacco, tomato, tree, triticale, turf grass, vegetable, watermelon, and wheat plants and cells.

Nucleotides sequences can be constructed that are useful for expression of these proteins in plant cells, and such plant cells can be regenerated into transgenic plants that can produce seeds containing such nucleotide sequences which can be commercialized, bred together with other transgenic plants expressing different Bt insect inhibitory proteins or other agents toxic to crop pests.

Plant cells can be transformed by multiple mechanisms that are within the skill of the art including but not limited to bacterial transformation systems such as Agrobacterium or Rhizobacterium, electroporation, ballistic mediated systems, and the like. Microprojectile bombardment methods are illustrated in U.S. Pat. Nos. 5,015,580 (soybean); 5,550,318 (corn); 5,538,880 (corn); 5,914,451 (soybean); 6,160,208 (corn); 6,399,861 (corn); 6,153,812 (wheat) and 6,365,807 (rice) and Agrobacterium-mediated transformation is described in U.S. Pat.

(1998) Transgenic Res. 7:213-222 (sugarcane) and other more recent methods described in US Patent Application Publications 2009/0138985A1 (soybean), 2008/0280361A1 (soybean), 2009/0142837A1 (corn), 2008/0282432 (cotton), 2008/0256667 (cotton), 2003/0110531 (wheat), U.S. Pat. Nos. 5,750,871 (canola), 7,026,528 (wheat), and 6,365,807 (rice). Transformation of plant material can be practiced in tissue culture on a nutrient media, e. g., a mixture of nutrients that will allow cells to grow in vitro. Recipient cell targets include, but are not limited to, meristem cells, hypocotyls, calli, immature embryos and gametic cells such as microspores, pollen, sperm and egg cells. Callus may be initiated from tissue sources including, but not limited to, immature embryos, hypocotyls, seedling apical meristems, microspores and the like. Cells containing a transgenic nucleus are grown into transgenic plants.

In addition to direct transformation of a plant material with a recombinant DNA, a transgenic plant cell nucleus can be prepared by crossing a first plant having cells with a transgenic nucleus with recombinant DNA with a second plant lacking the transgenic nucleus. For example, recombinant DNA can be introduced into a nucleus from a first plant line that is amenable to transformation to transgenic nucleus in cells that are grown into a transgenic plant which can be crossed with a second plant line to introgress the recombinant DNA into the second plant line. A transgenic plant with recombinant DNA providing an enhanced trait, e. g., enhanced yield, can be crossed with transgenic plant line having other recombinant DNA that confers another trait, for example herbicide resistance or pest resistance, to produce progeny plants having recombinant DNA that confers both traits. Typically, in such breeding for combining traits the transgenic plant donating the additional trait is a male line and the transgenic plant carrying the base traits is the female line. The progeny of this cross will segregate such that some of the plants will carry the DNA for both parental traits and some will carry DNA for one parental trait; such plants can be identified by markers associated with parental recombinant DNA, e. g., marker identification by analysis for recombinant DNA or, in the case where a selectable marker is linked to the recombinant DNA, by application of the selecting agent such as a herbicide for use with a herbicide tolerance marker, or by selection for the insect inhibitory trait. Progeny plants carrying DNA for both parental traits can be crossed back into the female parent line multiple times, for example usually 6 to 8 generations, to produce a progeny plant with substantially the same genotype as one original transgenic parental line but for the recombinant DNA of the other transgenic parental line.

In the practice of plant transformation, exogenous DNA is typically introduced into only a small percentage of target plant cells in any one transformation experiment. Cells of this invention can be directly tested to confirm stable integration of the exogenous DNA by a variety of well-known DNA detection methods or by a variety of well-known bioactivity assays that test for insect inhibitory activity (further described in the examples section). Marker genes can be used to provide an efficient system for identification of those cells that are stably transformed by receiving and integrating a recombinant DNA molecule into their genomes. Preferred marker genes provide selective markers which confer resistance to a selective agent, such as an antibiotic or an herbicide. Any of the herbicides to which plants of this invention can be made resistant can be used as agents for selective markers. Potentially transformed cells are exposed to the selective agent. In the population of surviving cells will be those cells where, generally, the resistance-conferring gene is integrated and expressed at sufficient levels to permit cell survival. Cells may be tested further to confirm stable integration of the exogenous DNA. Commonly used selective marker genes include those conferring resistance to antibiotics such as kanamycin and paromomycin (nptII), hygromycin B (aph IV), spectinomycin (aadA) and gentamycin (aac3 and aacC4) or resistance to herbicides such as glufosinate (bar or pat), dicamba (DMO) and glyphosate (aroA or EPSPS). Examples of such selectable markers are illustrated in U.S. Pat. Nos. 5,550,318, 5,633,435, 5,780,708, and 6,118,047. Markers which provide an ability to visually screen transformants can also be employed, for example, a gene expressing a colored or fluorescent protein such as a luciferase or green fluorescent protein (GFP).

Plant cells that survive exposure to the selective agent, or plant cells that have been scored positive in a screening assay, may be cultured in regeneration media and allowed to mature into plants. Developing plants regenerated from transformed plant cells can be transferred to plant growth mix, and hardened off, for example, in an environmentally controlled chamber at about 85% relative humidity, 600 ppm CO2, and 25 to 250 microeinsteins m 2 s-1 of light, prior to transfer to a greenhouse or growth chamber for maturation. These growth conditions vary among plant species and are known to those skilled in the art. Plants are regenerated from about 6 weeks to 10 months after a transformant is identified, depending on the initial tissue, and plant species. Plants may be pollinated using conventional plant breeding methods known to those of skill in the art and seed produced, for example self-pollination is commonly used with transgenic corn. The regenerated transformed plant or its progeny seed or plants can be tested for expression of the recombinant DNA and selected for the presence of insect inhibitory activity.

Transgenic plants encoding and expressing one or more of the proteins of the present invention are grown to (i) generate transgenic plants having an enhanced trait as compared to a control plant and (ii) produce transgenic seed and haploid pollen of this invention. Such plants with enhanced traits are identified by selection of transformed plants or progeny seed for the enhanced trait. For efficiency a selection method is designed to evaluate multiple transgenic plants (events) comprising the recombinant DNA, for example multiple plants from 2 to 20 or more transgenic events. Transgenic plants grown from transgenic seed provided herein demonstrate improved agronomic traits that contribute to increased insect inhibitory tolerance or increased harvest yield or other traits that provide increased plant value, including, for example, improved seed or boll quality. Of particular interest are cotton, alfalfa, corn, soy, or sugarcane plants having enhanced insect inhibitory resistance against one or more insects of the orders Lepidoptera and/or Hemiptera. Of particular interest are cotton plants having enhanced insect inhibitory resistance against an insect of the order Hemiptera.

The invention provides methods to produce a plant and harvest a crop from seed comprising a recombinant polynucleotide molecule encoding the insect inhibitory polypeptides of the present invention. Of particular interest are cotton, alfalfa, corn, soy, or sugarcane plants having enhanced insect inhibitory resistance against an insect(s) of the order Lepidoptera and/or Hemiptera. The method includes the steps of crossing an insect resistant plant expressing the recombinant polypeptides of the present invention with another plant, obtaining at least one progeny plant derived from this cross, and selecting progeny that expresses the recombinant polypeptides of the present invention wherein said progeny is resistant against an insect. This includes the steps of planting the seed, producing a crop from plants grown from the seed, and harvesting the crop, wherein at least 50% of the crop comprises seed comprising the recombinant polynucleotide molecule.

The agar base was melted and blended with diet and purified water to volume (1.4% (w/v) agar). Diet suspension was dispensed into individual bioassay compartments.

A test sample of recombinant protein TIC1886 was prepared as described in example 2, and overlaid over 24 compartmentalized diet surfaces approximating about 2890 ug/mL per compartment. A buffer control sample was overlaid onto 96 compartmentalized diet surfaces. Together, 120 compartmentalized diet surfaces comprise the test set of this example prepared for Helicoverpa zea bioassay.

Example 13: Protein Expression in Plants

This example illustrates expression of proteins of the present invention in plants. Polynucleotide segments for use in expression of the proteins of the present invention in plants can be produced according to the methods set forth in U.S. Pat. No. 7,741,118. For example, toxin proteins having the amino acid sequence as set forth in SEQ ID NO:4, SEQ ID NO:12, SEQ ID NO:18, and SEQ ID NO:26 can be produced in plants from polynucleotide segments having the sequence as set forth respectively in SEQ ID NO:27, SEQ ID NO:28, SEQ ID NO:29, and SEQ ID NO:30. Polynucleotide segments designed for use in plants and encoding the proteins of the present invention, including the sequences as set forth in SEQ ID NO:27, SEQ ID NO:28, SEQ ID NO:29, and SEQ ID NO:30 are operably linked to the requisite expression elements for expression in plants, and transformed into the genome of plant cells, preferably cotton, alfalfa, corn, and soybean cells.

It is intended that polynucleotide segments (or polynucleotide molecules) encoding each of the following enumerated proteins, insect inhibitory fragments thereof, and proteins exhibiting the degree of identity specified herein above to one or more of these enumerated proteins, be used alone or in combinations with each other, or in combinations with other toxin proteins or toxic agents such as dsRNA mediated gene suppression molecules designed to work in synergistic or synonymous ways with the proteins of the present invention, to achieve plants and plant cells protected from pest infestation, particularly insect pest infestation. The specific enumerated proteins within the scope of the invention include TIC1498 (SEQ ID NO:2), TIC1415 (SEQ ID NO:4), TIC1497 (SEQ ID NO:6), TIC1886 (SEQ ID NO:8), TIC1925 (SEQ ID NO:10), TIC1414 (SEQ ID NO:12), TIC1885 (SEQ ID NO:14), TIC1922 (SEQ ID NO:16), TIC1422 (SEQ ID NO:18), TIC1974 (SEQ ID NO:20), TIC2032 (SEQ ID NO:22), TIC2120 (SEQ ID NO:24), TIC1362 (SEQ ID NO:26), TIC2335 (SEQ ID NO:136), TIC2334 (SEQ ID NO:138) and insect inhibitory fragments thereof, such as but not limited to, TIC1497.34225 (SEQ ID NO:61), TIC1497.32557 (SEQ ID NO:62), TIC1497.34485 (SEQ ID NO:63), and TIC1497.32411 (SEQ ID NO:64).

For instance, proteins of the TIC1415 genus of the present invention can be combined with other pesticidal agents, including pesticidal agents targeting pests which overlap with pests targeted by TIC1415 proteins. Additionally, other pesticidal agents may include agents that target pests that do not overlap with pests targeted by TIC1415 proteins. In either case, it is intended that TIC1415 proteins be used alone or combined with other pesticidal agents. In the examples described below, TIC1415 was co-expressed with a TIC807 toxin protein in cotton plants and in planta bioassays were conducted. In addition to TIC807 toxin proteins, other pesticidal agents that can be used in combination with TIC1415 proteins include (1) hemipteran-centric agents, e.g. dsRNA directed towards hemipteran orthologs of Nilaparvata lugens V-ATPase-E, 21E01(Li, Re et al., 2011, Pest Manag Sci); dsRNA directed towards hemipteran orthologs of five different genes—actin ortholog, ADP/ATP translocase, α-tubulin, ribosomal protein L9 (RPL9) and V-ATPase A subunit (Upadhyay, S. K., et al., 2011, J. Biosci. 36(1), p.153-161); AXMI-171 (US20100298207A1); Bt endotoxins such as Cry3A, Cry4Aa, Cry11Aa, and Cyt1Aa, which were found to exhibit low to moderate toxicity on the pea aphid, Acyrthosiphon pisum, in terms of both mortality and growth rate (Porcar, M. et al., Applied and Environmental Microbiology, July 2009, p.4897-4900, Vol. 75, No. 14); (2) other Coleopteran pesticidal agents, e.g. DIG11 and DIGS; Cry7; eCry3.1Ab; mCry3A; Cry8; Cry34/Cry35; and Cry3 toxins generally; and (3) other Lepidopteran pesticidal agents, e.g. DIG2; Cry1 toxins; Cry1A.105; Cry2 toxins, particularly Cry2A toxins; Cry1F toxins; VIP3 toxins; and Cry9 toxins. Transgenic crop events expressing other pesticidal agents can also be used in combination with crop events expressing TIC1415 proteins, examples of which include MON88017, MON89034, MON863, MON15985, MON531, MON757, COT102, TC1507, DAS59122-7, 3006-210-23, 281-24-236, T304-40, GHB119, COT67B, MIR162; corn event 5307, and the like. Such combinations with events expressing one or more proteins of the TIC1415 genus proteins provide more durable pest protection, provide a resistance management strategy for target pest control, and reduce farmer inputs, saving considerable expense in time and monetary value.

Recombinant plants are generated from transformed plant cells of this example, and the recombinant plants or their progeny are evaluated for resistance to pest infestation, such as tolerance to Hemiptera and/or Lepidoptera. Transgenic plants and seed are selected that provide pest resistance, such as to Hemiptera and Lepidoptera, and such plants and seed are advanced for further development.

Example 14: In-Planta Bioassay of TIC1415

In this study, toxin protein TIC1415 having the amino acid sequence as set forth in SEQ ID NO:4 was produced in plants from polynucleotide segments having the sequence as set forth in SEQ ID NO:27. DNA having the sequence of SEQ ID NO:27 encoding TIC1415 was cloned into an Agrobacterium-mediated plant transformation vector along with requisite promoter and regulatory elements for transformation and expression in cotton cells. Transgenic cotton plants (recombinant cotton plants) were produced and tested for efficacy. Regenerated (R0) transgenic plants were transferred to soil and tissue samples selected from transformation events that were low in copy number and expressing TIC1415 protein. Lyophilized tissue samples of R0 plants from three events were weighed and combined 1:50 and 1:100 (weight:buffer) of 25 mM Sodium-carb/bicarb buffered at pH 10.5 to extract soluble protein from the tissue. Samples were confirmed by Western blot for presence of TIC1415 protein. Sample extracts were fed to Lygus lineolaris using the bioactivity assay described in Example 8. Extract from DP393 cotton tissue absent of TIC1415 protein was also prepared as negative control. Sample extracts from all three events exhibited mortality against Lygus lineolaris and survivors were stunted. Mortality and stunting scores were significant compared to bioactivity scores of insects fed with sample extracts from the DP393 negative control.

R0 plants were grown and self-pollinated to obtain seed homozygous for the introduced transgenic DNA. Homozygous plants from three different single copy events were selected and five seed per event planted and evaluated in a whole plant caging assay. Plants were grown to flowering stage and each whole cotton plant was enclosed in a mesh cage made from perforated plastic. Two pairs of male and female Lygus hesperus adults were placed into each cage and allowed to reproduce. Resulting insect progeny were allowed to infest the caged cotton plants for 3 weeks. At the end of the 21 day period, Lygus insects at various stages of development were counted and average means calculated on a per plant basis. Plants from all three events had significantly less insects compared to the DP393 negative control. See Table 4.

Example 15: Protein Bioassay of TIC1415 and a TIC807 Hemipteran Toxic Protein

Protein samples were prepared containing various mixtures of TIC1415 and a TIC807 hemipteran toxic protein and tested in bioassay. TIC1415 protein alone and the TIC807 protein alone were also prepared as positive controls. Buffer was used as negative control. Sample mixtures were fed to Lygus lineolaris using bioactivity assay. All three preparations containing toxin protein exhibited mortality against Lygus lineolaris and survivors were stunted. Mortality and stunting scores were significant compared to bioactivity scores of insects fed with buffer (see Table 5). The data suggests that there are no antagonistic effects. Additional bioassay tests are performed on mixtures to demonstrate synergistic and/or additive effects.

Example 16: In-Planta Bioassay of TIC1415 and TIC807

Transgenic cotton events were designed to co-express respective proteins TIC1415 (SEQ ID NO:4) and a TIC807 protein. Such plants were evaluated in a caged whole plant assay infested with Lygus lineolaris. Five plants each from ten events were caged and infested with 2 pairs of male and female L. lineolaris per plant. The assay was incubated in a growth chamber under normal environmental conditions for cotton plant development for 21 days. DP393 negative control plants were grown in similar manner. At the end of the 3 week period, Lygus of various stages of development were counted. The mean number per plant of Lygus hesperus insects at each stage in development were calculated and the results are shown in Table 6. Therein, different plant-expressible promoters were used to drive expression of the transcript encoding TIC1415 in the respective constructs 12 and 13.
